OriginaI'appIieation filed May 19, 1908, Serial No. 433,664. Divided and this application filed April 19, 1909. Serial No. 490,698.

To all whom it may concern: I

' Be it known that I, FELIX Khan, a subject of the Emperor of Germany, residing at Bellevue, in the 'county of Allegheny and State of Pennsylvania,- have invented cer-- The present application relates to improvements in the end construction of the underframe ofcars, such structure being.

especially ,adapted for use in passenger cars, but is adapted for use also 111 freight car construction.

The invention is clearly shown inthe ac-.

in which like refer companying drawings,

and m ence characters refer. to like parts, WlllCl'l- Figure 1 is a plan view of a portion of a car underfranie embodying the details of the invention; Fig. 2 is an end elevation of the same; Fig. 3 is a longitudinal section on line 3-3, Fig. 1; and Fig. 4 is a like view on the line 1-4, Fig. 1.

An object of construction of the underframe embodying improvements in details of the connection between the center sills and the end sill of the car, and a means for bracing said parts at or near such connection.

Referring now in detail to the 'drawlngs: 1 are channel center sills secured through means of horizontal flanged gusset plates 3;

the present invention is to i provide an improved shock resisting end center sill brace secured by means of its legs to center sills lwith its apex toward and near the end sill 2; 10 is abell coupler, or coupler of other suitable shape, secured by means of the bolt 11 to the apex of brace 9; 12 is a coupling link; and 13 the coupling pin located in a perforation in the coupler 10 holding the link 12 therein. The gussets 3 may be flanged downwardly, if desired for the purpose of securing them to the'end sill 2 as shown in the drawing. The brace 9 is deepest vertically at its forward or apex portion, at which point it is suitabl de-.

signed to take care of any bufiing siocks which might come upon the coupler 10, and

at the same time look after the pulling strains to which it is subjected and which it transfers directly to the-center sill construction of the car or sills 1. 'The cross braces 7 and 8 guard against an tendency of the center sills 1 to buckle ue to any balling shocks which they might sustain.

An advantage of the present construction is that it constitutes a light, strong and inex ensive construction.

aving thus described my invention, the following is what I claim as new therein and desire to secure by 'Letters Patent:

In a car, an end sill, a bell coupler having a flange bearing against the 'outer face of said end sill and a tapered portion ex-' securing said bell coupler and said braces to each other at their apices. V In testimony whereof I aflix my signature in presence of two witnesses.
